HAY-UNLOADING nrrnnnrus.

To all whom it mayconcem:

Be it known that I, ALBERTULOH, a citizen of the United States, residingat Chelsea, in the county of Tamaand State of Iowa, haveinventedcertainnew and useful Improvements in Hay-Unloading Apparatus, of which thefollowing is a specification, reference being vhad to the accom panyingdrawings.

" unloading apparatus and has for its. pri- It is a further objectoftheinvention to provide an apparatus for the above purpose, which is simplein its construction,.highly serviceable and convenient inpractical use,and maybe manufactured and installed at relatively small cost. I

With the above and other objects in View, my invention consistsin thenovel features of construction, combination and arrangement of parts tobe hereinafter more fully described, claimed and illustrated in the accompanying drawings, in Which, t t Figure 1 is a side elevation of myimproved yhay unloading apparatus" showing the carriage in itsdischargeposition within the barn; Fig. 2 is a similar view, thecarriagebeing disposed exteriorly of the barn in its load receivingposition; Fig. ,3 is an elevation on an enlarged scale of the weight edcable pulleys, illustrating the connections of the cables; Fig. is aside elevation of the drumcoperating gearing; and Fig. 5 is a topplanview thereof. l

Referring in detail to the drawings, 5 designates a longitudinallyextending track Specification of Letters Patent;

This invention relates to an improved hay which is suitably mounted inthe top of the barn and at one of its ends extends exteriorly thereof.Upon this track, the traveling carriage 6 is arranged and is provided.with a hay fork indicated at 7. The

track, carriage and fork may be of any or- I dinary or approvedconstruction, said fork being equipped with the usual trip devicewhereby its load may be released. 8 indi cates the cord extending fromthe trip device, wherebythe same may be actuated.

Upon the inner end of the elevated track 15, afpulley or sheave 9 issuitably; "mounted, and asecond pulley or sheave 10 is also supported bythe track adjacent to the pulley 9.

11 indicates a suitable yoke or frame in I which a pair of pulleys 12are rotatably mounted,the axes of said pulleys being in verticalalinement. To the lower, end of this yoke frame, suitable weights 13].are

tional pulley 14 is mounted in bearing arms 15 depending from the frame12. Ina suit able support 16 fixed to the floor or other suitablestationary part ofthe barn structure, a pair of pulleys 17 are rotatablymounted. "One end of a rope or cable 18 fixed, and between these weightsan addiis attached to a bail 19 depending from the axis of the pulley14:. This cableiis carried downwardly. around the uppermost pulley 17,and then upwardly around the pulley 14 and again downwardly and aroundthe lower pulley 16. From this lower pulley, the cable 18 is extendedaround suitable guide pulleys indicated at 20, and attached to onesection of a double drumshown at 21 whichis suitably mounted upon theforward end wall of the barn. The operating means for this drum will behereinafter described. Acable 22 is also attached at one of its ends tothe other section of the drum 21 and passes around a guide pulley 23 andthen rearwardly over the guide pulley 9, said cable extending downwardlyfrom" this guide pulley and around the lowermost pulley 12 and thenupwardly around the pulleylO, and from the pulley ,lOthe cable extendsdownwardly around the upper pulley 12 and again 'upwardly,and is fixedat its end'to a bail or loop indicated at 24. A second cable 25 is alsoattached to this bail and extends downwardly around the upper pulley 12and then upwardly over the pulley 10 and against downwardly and aroundthe lower pulley 12 and upwardly over the pal-- ley 9. This cable isextended from the latter pulley over a pulley 26 mounted on thecarriageffi and under a sheave 27 from which the hay fork is suspended,the end of the cable being suitably secured to one 1 end of thecarriage. A cable 28 isalso attached to the forward end of the carriage6 and extends exteriorly of the barn over a supporting sheave 29 mountedon the exfixed, and with the same a manuallypperable gear 3 L meshes,said gear having a crank handle 85. I p

36 designates guide loops for the cables which are wound upon the drumsections, and it will be noted that the cable which is connected to theweighted pulley block extends around its drum section in onedirectionwhile the other cable 22 extends around the other drum sectionin a relatively opposite direction. It will thus be apparent thatwhenone of the cables is unwound from the drum, the other cable is woundthereon.

In the operation of the device, it will be understood that the weightedpulley carrying block to which the cable 24 is connected, normally tendsto pull the carriage inwardly to the inner end of the track 5. Assumingthat the hay fork has been supplied with a load of hay, the operator,upon turning the crank of the gear 34C to the right, rotates the drum sothat the cable 22 will be wound tation of the gear 3-4, the cable 22will unwind from the drum while the cable 24: will be wound thereon,thus elevating the pulley block. The weighted pulley 30 on the end ofthe cable 28 will thusmove downwardly upon the guide cord or cable 32and the carriage and hay fork will be moved outwardly along the track 5into position to receive anotherload of hay. In this manner, it will beseen that the device may be operated entirely by one man, and thecontents of the hay rack easily and quickly loaded into a barn.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, manner of operation and severaladvantages of the invention will be fully understood. The memberindicated at 37, fixed to the under side of the track at its outerend,,is for the purpose of operating the latch device which holds thehay fork in connection with the carriage so that the hayfork may bepulled downwardly in position to receive the load.

It will be appreciated that the apparatus as a whole is comparativelysimple in its construction and can be readily installed in an ordinarybarn at nominal cost. It will be apparent that the several operatingparts of the apparatus may be otherwise mounted and'arranged than asabove referred to, and

the detail structural features'of these parts may be variously modifiedand I, therefore, reserve the privilege of adopting allsuch legitimatechanges as will fairly fallwithin the spirit and scope of the inventionas claimed.

Having thus fully described my invention,

what I desire to claim and secure by Letters Patent is e r I 1. Ina hayunloading apparatus, the combination of a track extending interiorly andexteriorly of a barn, a carriage to travel upon said track, a pair ofweighted pulleys, cables passing around said pulleys, guides forthecables, one of said cables being connected to the carriage, a manuallyoperable drum, the other of the cables being attached to the drum to bewound thereon, an additional cable connected to the weighted pulleys atone of its ends and'also attachedto the drum to wind thereon in anopposite direction with respect to the first named pulley, and means formanually rotating the drum in either direction to raise or lower theweighted pulleys and permit the carriage to travel in either directionupon the track.
